FRANK 'I.'STUART, OF MAPLEWOOD, NEVJ JERSEY, ASSIG-NOR TO THE NEUMANN HARDWARECQ, A CORPORATION OF NEW JERSEY.

BAG-FRAME FASTENER.

Application filed. August 12, 1924. Serial No. 731,624.

To all whom it may concern Be it known that 1,-F11ANK .T. STUART, a citizen of the United States, residing at Maplcwood, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Bag- Frame Fasteners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art towhich it appertains to make and use the same, reference being had to the accompanying drawings, and to characters of reference marked thereon, which form a part of this specifica tion. i

@LThis invention relates, generally, toimprovements in bag-frame fasteners, and,the present invention has reference, more particularly, to a novel construction of safetycatch for the hinged frame-sections of a bagframe, with a view of providing a simply constructed and positively acting construction, the parts of the fastener having been reduced toa minimum, and the parts of the fastener being arranged so that they will act automatically to maintain a locked relation ofthe parts of the fastener, when the hinged bag-frame sections are closed, but being readily manipulated, to bring the parts of the fastener into their unlocked relation, so that the frame-sections may be brought into their separated or opened relation. i I

The present invention, therefore, has for its principal object to provide a bag-frame fastener of the general character and construction hereinafter more fully set forth, and having for its main purpose an automatic clocking action of itsmechanism for maintaining the bag-framesections in their closed relation. I

Other objects of the present invention not at this time more particularly enumerated will be clearly understood from the following detailed description of the present invention.

With the various objects 'of the present invention in view, the said invention consists, primarily, in the novel bag-frame fastener hereinafter more fully set forth; and, the invention consists, furthermore, in the novel arrangements and combinations of the devices and parts, as well as in the details of the construction of the said parts, all which will be more fully described in the following specification, and then finally embodied in the clauses of the claims, which are appended to and which form an essential partof the said specification.

The invention is illustrated in the panying drawings, in which Figure 1 is a top edge-view of the two frame-sections of a bag-frame, said framesections being shown in their disconnected relation, one of said frame-sections illustrating in connection therewith an arrangement of a pair of. fasteners embodying thep'rinciples'of the present invention, and the other frame-section being shown with a pair of hasp-members adapted to be moved into locking engagement with the mechanism of said fasteners, the push-membersor bolts of the fasteners beingrepresented in their manually actuated positions for releasing the hasp-niembers from their locKed engagement with the. mechanism of the fasteners. Figure 2 is a top-edge view of a portion of the frame-section provided with the frame-fasteners, showing in 1 connection therewith a fastener having its push-man her or boltinthe position, when the parts of the inner mechanism of the fastener are in locked relation with, one another.

Figure 3 is a. top-edge view of a fragmentary portion of the frame section, and a bottom or base-plate secured thereto, the main shellor casing of the fastener,.with its contained mechanism, being omitted from said view; and Figure 4 is a similar view of one portion of the frame-section represented in said Figure 3, with the bottom or base plate removed from the frame-section.

Figure 5 is atransverse vertical sectional representation taken on line 5-5 in Figure 1; Figure 6 is a horizontal sectional representation of the various parts, said section being taken on 1ine,66in said Figure 5, looking in the direction of the arroww; Figure 7 is a view, similar to said Figure 6, illustrating the inner mechanism of the fastener in. its lockedengagement with the hasp-membergand Figure 8. is a, longitudinal vertical section of the device, said section being taken on line 88 in said Figure 5, looking in the direction of the arrow 1/.

Figure 9 is a perspective view of the pushmember, or bolt of thesaid bag-frame fastenor; :and FigurelO is a similar view of the base-plate of the same.

Figures 11 and 12am views, similar to Figures 6 and 7, respectively, of a modified construction of bag-frame fastener.

Similar characters of reference are employed all of the said above-described views, to indicate corresponding parts.

Referring now to the several figures of the drawings, the reterence characters 1 and 2 indicate the frame-sections of a bag-frame, which are of any of the usual constructions,

and whicharc adapted. to be pivotally connected in. the usual and well-known man nor. To one of said frame-sections, as 2, is suitably secured by means of rivets 3, or otherwise, a hasp-plate 4t havingan. up-

1 wardly extending member 5 from which extends, at. a right angle, a hasp-member 6 provided with a laterallyextending receiving notch or slot 7, and a spring engaging end portion 8, substantially as shown in the 0 several figures of the drawings, the same being adapted, to be moved over and above the frame-section 1 and enter the shell or casing ofthe bag-frame fastener for engagement with the. hasp-engaging mecha 25 nism within said shell or casing, in the manner to be presently more fully described.

The. form of bag frame. fastener shown more particularly in Figures 1 to 10 inclusive, consists, essentially, of a main shell 32 or casing comprising a top 9, a pair of said end-walls 12 and 13 being respectively provided with fastening lugs 15, which extend into and are passed through correspondingly shaped slits or openings 1'1 of abase-plate 16 disposed against the marginal edges of the side-walls 10 and '11, and theend-walls 12 and 13,01 thesaid shell or casing, as indicated in Figures 5 and 8 of the drawings. That the, said shell or casing, with its base-plate 16, may be secured upon the outer face of the frame-section. 1, the said fastening lugs 15,, are also passed through correspondingly located slits .18 in the framesection 1 and then bent over upon the under face of said'frmne-section, in. a manner as indicated in said Figures 5 and 8. of .the drawings}.

, The reference-character 19, indicates a suitably shaped bolt, in the. formof a push or slide-plate, which is longitudinally dis.- posed within the chamber of the said shell or.casi.ng, the said plate having its respective end-portions 20 and 2-1 extending into and through suitably disposed guiding openings or slits 22 and 23' in the respective endswalls 12 and 13 of the said shellor casing, and the projecting parts of the said end-portions 20 and 21 being respec tively provided with angular members 24 and 25, one of which, as, 24, serves as a push or iingerpiece, and the other member 25 serving as a stop, as will be evident more particularly from an inspection of Figure 7 of the drawings. In addition, the push or slide-plate 19'is provided with a pair of suitably disposed studs or posts 26 and 27, and also with a projecting portion 28, which is provided with a hasp-engaging flange 29, one end of which, nearest the end-wall 13 of the shell or casing, is provided with a bent portion, as 30.

Disposed between the inner face of the said end-wall 13 and the said bent portion 30 are the arms or members of a U-shaped spring 31. The reference-character 82 indicates another spring, comprising a pair of arms or members 33 and 345, connected by means of an angularly formed portion 35, and with the edge-portion 36 of which, underv normal conditions, when the framesections 1 and 2 have been brought into their closed relation, the spring-engaging end 8 of the hasp member 6 has been brought into engagement.

'leierring now to Figure 6 of the drawings, in which the parts of the inner ,mechanism are shown in their manually operated positions, when the slide-plate 19has been forced by the operator exerting pressure upon thepush or fingerpiece 24; in the direction of the arrow 2, and in which figure the hasp-inember 6 is shown in its with drawn relation from the said mechanism, the parts of the mechanism being held in the positions shown by the engagement of the portions ,36 and oi the spring 32, respectively, with the studs or posts 27 and 26, as soon as the hasp-member 6 enters the opening 14 in the side-wall 10, as the framesections are being closed,,the portion 8 on gages the ed e-portion 36 of the spring 52, thereby forcing the angular portion'35, clear of the stud or post 27. Immediately, the compressed members or arms of the spring 31 become active, thereby causing the slideplate 19 to be moved into the position indicated in Figure 7 of th drawings, with the hasp-engaging flange 29 of the said plate having entered the, notch or slot 7 of the hasp-member, so that all of the various parts, as well as the closed frame-sections. 1 and 2 will be maintained in their closed and locked relation.

The, stop-member 25 in coming in con tact with the outer face of the end-wall 13 of the shell or casing limits the closing movement of the slide-plate 19, as will be clearly evident. To again, bring the frame-sections 1 and 2 into their open relation,.and to separate the hasp-member 6 from its locked. engagement with the flange 29' of the slide-plate 19, all that the operator has to dois to apply pressu s upon the push or fingerpiece 2st, thereby changing the rclative positions of the parts of the mechanism, asv indicated in Figure 7 of the drawings, to the positionsishown Figure adapted to engage, as shown in Figure 11,

the shell 0r casing, in this instance, being provided with a third spring 38 secured to the inner face ofthe sidewall 10, as at 39, the free end-portion of this spring hear ing forcibly upon ,an edge-portion 40 of the'hasp-member 6, when the various parts arein their locked relation, as indicated in Figure 12 of the drawings, but said spring 38 permitting the hasp-plate-tohe operated when the slide-p'latelt)" is manually manipulated, as previously described, and for the release of the' said hasp-rnember with the engaging flange 29 of the said slide-plate,

as will be fully understood from an inspection of said Figures 11 and 12 of the drawings.

Otcourse I am awaretl'iat the device is capable of other changes inthe general arrangements and combinationof the devices and parts, as wellasin the details of the construction of the same,withoutdeparting from the. scope of the present invention, as set forth in the foregoing specification, and as defined in the clauses of the claims which are appended thereto. Hence, I do not limit my present invention to the exact arrangements and COITlbllflfillOIlSbf the said devices and parts, asdescrlbed lnthe sald specification, nor do I confine myself to the exact details of the constructiono'f the said parts, as illustrated in the accompanyingdrawings. v Iclaimz-fl 1.
